Russian Energy Minister Alexander Novak intends to discuss with European Commission Vice President Maros Sefcovic in charge of the Energy Union the situation with Ukraine's natural gas reserves in its underground gas storage facilities. The Russian TASS agency reports this citing of Russian Energy Minister Novak, Ukrainian News Agency reports. "Ukraine has pumped to its underground gas storage facilities 14.7 billion cubic meters of gas, although at least 17 billion cubic meters is needed. Ukraine will not have enough volume of natural gas in the underground gas storage facilities to provide the transit. We have been instructed to hold negotiations. We are negotiating a date of arrival in Russia of Sefcovic. We will discuss reliable passing of the winter period in Ukraine. Major periods of the risk are January - February," said the minister. Novak believes there is a risk that Ukraine will lack funds to pump gas to the underground gas storage facilities when the temperatures are low. As Ukrainian News Agency earlier reported, Ukraine took 479.637 million cubic meters of natural gas from its underground gas storage facilities during the first month of the heating season (since October 12, when the amount of natural gas taken from the underground facilities exceeded the volume of natural gas pumped into the underground facilities). As at November 12, the underground gas storage facilities had 14,252.39 million cubic meters of natural gas, against 16,904.81 million cubic meters on the same date of 2015. The Naftogaz of Ukraine national joint stock company says there is enough gas in the underground gas storage facilities to come through the heating season. Naftogaz of Ukraine plans that the underground gas storage facilities will have 7-8 million cubic meters of gas at the end of the heating season while 5 billion cubic meters is technically admissible. During the 2015-2016 heating season Ukrtransgaz began to take natural gas from underground gas storage facilities on October 30, 2015. The gas reserves then made 17.064 billion cubic meters. The underground gas storage facilities had 8.437 billion cubic meters on April 6, 2016.
